Get a solid grounding in chemistry and biology and still have lots of room to explore environment related courses in ecology, aquatic ecosystems, geology, hydrology, and more. You’ll learn about climate change, groundwater flow and contamination, environmental impacts of pollution, responsible extraction of Earth resources, waste disposal, and human engineering of Earth processes. Specialize in Ecology to address ecological sustainability and biodiversity while learning about the fundamental science of life on Earth. Go the Geoscience route and focus on the interactions among the geosphere, hydrosphere, atmosphere, and biosphere as well as the human activities that encompass the complex and dynamic Earth System. Or choose the Water Science specialization and investigate the unique properties of water; the distribution and movement of fresh and salt water above, on, and within the Earth; and the quality and quantity of water that humans depend upon to survive and thrive on this planet.Environmental science applies geologic knowledge to address and solve problems related to the more than seven billion humans occupying the Earth.
